Description

^ / ^ 25 、 Explanation of the invention (1) 5 ~ 1 Field of invention: The present invention relates to a scanner for scanning diodes. σ 'especially relates to the background with organic light emission 5 ~ 2: Traditionally, scans are scanned on scan reflections, such as workers' and broom scanners can be divided into two types, one is placed on the scanning port with a light source 2 and scanned by f As shown in the first figure, it is, for example, shown in the second figure = f body. The other is used to scan through the space created by the manuscript. These two types are placed in the upper case 4 and the broken glass plate 7 as light sources 'as shown in Figure 2-2 and in the Figure 5 V. Cooling: in extremely fluorescent lamps (CCFL) devices' CCFL light sources need to be first Irradiate on some traditional scanning mirrors located in the basin f to collect light, such as backlight sticking, and then, 隹 —long strip concave focal lens, etc., travel with a known light path, the most enter the mirror group, focus The device (CCD) senses its image and completes the entire imager, such as electrical coupling. However, the disadvantages of using CCFL as the light of the scanner are as follows:

1. As shown in the third figure, 'When the light source passes the effect of the focusing lens Θ (ie, the lens effect), the strong light source around the light source is reduced due to cos4 a 8 series, resulting in 475325 5. Description of the invention (2) Light sensor The sensed wave of 诂 梆 π is not good. Therefore, after passing through the focusing lens, it is necessary to perform intensive actions such as supplementing light or obscuring to supplement the intensity around the light source and reduce the lens effect to obtain better image quality. 2. The low temperature characteristics of CCFLk sources are unstable. At low temperatures, the scanner needs a longer warm-up time. '3. Scanners using CCFL light sources require greater power. Generally speaking, CCFL light sources require 4 to 5 watts of power. Therefore, it is necessary to use an external power supply to supply CCFL light sources. That is, a scanner that conventionally uses a CCFUf source requires an external power supply in addition to, for example, a universal series bus (USB) power supply. 4. Due to the unstable low-temperature characteristics of CCFL light sources and their large power, the traditional sweep using CCFL light sources is crying from r '. Brother Shou Tian Jie's application is limited. According to this, to provide a scanning scan with improved structure, lack, and will not significantly increase the complexity of the process = to overcome the need of the above technology. /, 'Cost' is the current purpose and summary of 5-3 inventions: 5.

Element Ϊ: = emitting diode (〇LED) includes three organic light emitting = = =:; ::, green and blue light. Refer to the structure of an organic light-emitting element of a Takaoka type organic light-emitting diode. The organic light-emitting element is formed on a substrate 101, and the base # is also made of a transparent material, such as a glass plate. This organic light-emitting element layer is the bottom electrode 102 of the factory. In a specific embodiment of the present invention, although the 102 series functions as an anode, it may be formed of a ^ (一 Tin 〇x ide) layer with a thickness of 950 angstroms, which is usually grounded. An organic material layer 101, which functions as a hole pass layer (HTL), is formed on the bottom electrode. "It can be a TPM PTCDA with a thickness of 300 angstroms. A hole injection layer 104 can be selectively formed on the hole conductive layer 103. An organic layer functioning as one of the electron conducting layer (ETL) and the electron emitting layer (EL) is formed on the hole conducting layer 103. The electron-conducting layer and the electron-emitting layer can be selectively separated into two layers 105 and 106. The electrical continuous layer 107 located above the electron conductive layer 105 functions as a cathode and is connected to a driving voltage 108. The cathode can be made of Mg: Ag alloy (mass ratio 5 ·· 1) or high purity metal with a thickness of 2000 Angstroms.

This electron-conducting layer and hole-conducting layer are combined to generate electron excitation: to the electron-emitting layer, where the two kinds of carrier junctions can be changed. For example, the light intensity in the middle part can be reduced more than its focusing element. After that, the ambient light intensity. Any of the electron emitting layers. The scanner's image shoots the red, green and blue light element driving voltage settings (CCD). For this, the electronic middle part that can improve the emission of the light emitting element is not necessary, that is, the quality of the stack is adjustable.

Furthermore, the light emitting device makes the image light sense any layer in the middle of the image quality layer to be organic. Therefore, the light changes dynamically. The light emitted by each sensor of the sensor to the same part is used as the light source. In the transparency of the organic invention, one has, for example, an electric voltage composition system, and the light source is coupled with a light source through a strong light source mirror effect around the source. The invention also has the following advantages: (1) Organic light-emitting diodes need an external power supply for the library: =, the light source device (bus power s) of the invention is sufficient to supply the two sources of the invention. total work required
